European Gemlogical Laboratory

EGL USA is one of the largest and oldest independent gemological institutions focusing on gemstone certification and research. Originally part of an international network founded in Europe in 1974, EGL USA opened its first U.S. lab in the heart of New York's international diamond and jewelry district in 1977.

In 1986 EGL USA became independently owned. Today the EGL USA Group has laboratories in New York City, Los Angeles, Vancouver, and Toronto.

EGL USA is not affiliated with any other EGL labs outside North America. Every certificate issued by our lab states "A member of the EGL USA Group."

Certificate numbers are preceded by either "US" or "CA," to indicate country of origin and to provide consumers the assurance that their certificate has been issued by a member of the EGL USA Group.

In 1999 EGL USA initiated a Research Department to respond to the changing needs of the jewelry industry. It is one of only a few labs worldwide doing advanced research in gemology.

RESEARCH:

EGL USA is the only independent North American laboratory with a self-funded gemological research department. Through in-house investigations, field sampling, and collaboration with leading scientists from the physics, geological, and mineralogical worlds, our research team has revealed new insights into issues of major concern to the jewelry trade.

EGL USA is one of few labs specializing in diamonds that is doing research, grading and education on high pressure high temperature (HPHT) treated diamonds. In 1999, when the first HPHT treated diamond entered the commercial market, EGL USA initiated a major research effort to specifically address HPHT detection issues. Its ongoing efforts have led to the development of highly reliable identification procedures and a significant database on HPHT diamonds.

In 2003 the JCK Jewelry Industry Fund awarded EGL USA a significant research grant for its ongoing work in the identification of natural and synthetic diamonds modified by high pressure high temperature treatments.

As new gemological challenges arise, its research team has undertaken studies in other areas, such as:

The stability of irradiated diamonds

Treatments of colored stones

Rough diamond studies

Cut studies

Valuation studies of HPHT diamonds

Synthetic diamonds

Pearl identification
